Title: Dielectric properties of layered FeGaInS{sub 4} single crystals in an alternating electric field

Abstract

The results of investigations of the frequency and temperature dependences of dielectric losses and the imaginary part of the dielectric permittivity in FeGaInS{sub 4} single crystals are presented. Their experimental values are determined. It is established that the loss tangent and the imaginary part of the permittivity of FeGaInS{sub 4} single crystals in a field with frequencies of 10{sup 4}–10{sup 6} Hz decrease inversely proportional to the frequency (tanδ ~ 1/ω), and the conductivity is characterized by the band–hopping mechanism. For FeGaInS{sub 4}, the relaxation time is calculated, and it is established that there is a mechanism of electron polarization caused by thermal motion in this crystal.

  • We report on the reproducible growth of (Cu{sub 1-x}V{sub x})V{sub 2}S{sub 4} single crystals of sizable dimensions ({approx}0.3 mm) and homogeneous composition (x{approx}0.3) by means of high-pressure synthesis. The refinement of single crystal X-ray diffraction data indicates that the crystal structure is of the monoclinic defect NiAs-type, which consists of a stacking of VS{sub 2} layers with CdI{sub 2}-type structure and chains of edge-sharing (Cu{sub 1-x}V{sub x})S{sub 6} octahedra. Layers and chains form a network of face-sharing octahedra with no Cu-V intra-chain ordering. A combined X-ray photoelectron spectroscopy and bond valence sum analysis indicates that the valence of the Vmore » and Cu ions are 3+ and 1+, respectively. Magnetic susceptibility measurements unveil the coexistence of a large Pauli-like and of a small Curie-like paramagnetic contributions, with no evidence of any long range order down to 2 K. This result suggests a picture of predominantly itinerant 3d V electrons with significant electron-electron correlations. - Graphical Abstract: Crystallographic structure of (Cu{sub 0.69}V{sub 0.31})V{sub 2}S{sub 4}. For clarity, the octahedral environment of (Cu{sub 0.69}V{sub 0.31}) site is not shown. Highlights: > Synthesis of new single-crystals in the Cu-V-S system using high pressure and high temperature. > Structural analysis revealed the single-crystals to be of the defect NiAs-type structure. > Bond valence sum analysis combined to X-ray photoemission spectroscopy revealed Cu{sup 1+} and a majority of V{sup 3+}. > Magnetic susceptibility has been measured. > Charge carriers are of two types, localized and itinerant.« less
  • The results of studying the effect of a high electric field on the conductivity of MnGa{sub 2}S{sub 4}, MnIn{sub 2}S{sub 4}, and MnGaInS{sub 4} single crystals are reported. The activation energy is determined in high and low electric fields. It is established that the decrease in the activation energy with increasing the external voltage is associated with decreasing the depth of the potential well, in which the electron is located.
  • We have grown high-quality single crystals of the triple-layered perovskite ruthenate Sr{sub 4}Ru{sub 3}O{sub 10} using a floating-zone (FZ) method and measured their electronic transport and magnetic properties. Our experiments results are consistent with those previously reported for Sr{sub 4}Ru{sub 3}O{sub 10} flux crystals; the magnetic ground state of Sr{sub 4}Ru{sub 3}O{sub 10} is poised between an itinerant metamagnetic and itinerant ferromagnetic state, and its electronic ground state is a Fermi liquid. In addition, we have investigated the effect of disorder on the metallic state of Sr{sub 4}Ru{sub 3}O{sub 10}. From resistivity measurements of various Sr{sub 4}Ru{sub 3}O{sub 10} crystalsmore » with different levels of disorder, we found that disorder enhances both temperature-independent elastic scattering and also temperature-dependent inelastic scattering. The in-plane metamagnetic transition is also found to be sensitive to disorder. Disorder results in an increase in the metamagnetic transition field and different magnetic behavior above the transition. We discuss the implications of this interesting observation.« less
  • Research on polycrystalline RRh{sub 4}B{sub 4} samples has shown that crystalline electric field (CEF) effects play an important role in these compounds. The successful synthesis of single crystal samples of RRh{sub 4}B{sub 4} with R = Y, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Lu has provided an opportunity to further investigate CEF effects in these materials. Magnetization and magnetic susceptibility measurements on the RRh{sub 4}B{sub 4} single crystals revealed strong magnetic anisotropy, and the experimental results could be described well by CEF calculations based on the parameters derived from an analysis of experimental data for ErRh{sub 4}B{sub 4}more » single crystals. The easy directions of magnetization of these compounds are consistent with the signs of the Stevens factor {alpha}J of the CEF Hamiltonian. A strong influence of magnetic anisotropy on superconductivity was also observed.« less
